A bekah for every man, that is, half a shekel, after the shekel of the sanctuary, for every one that went to be numbered, from twenty years old and upward, for six hundred thousand and three thousand and five hundred and fifty men.
a beka a head (that is, half a shekel, by the shekel of the sanctuary), for everyone who was listed in the records, from twenty years old and upward, for 603,550 men.
This silver came from the tax collected from each man registered in the census. (The tax is one beka, which is half a shekel, based on the sanctuary shekel.) The tax was collected from 603,550 men who had reached their twentieth birthday.
